can someone please tell who wrote this and when was this written?
Moderator's reply: Thank you for visiting wiseGEEK. We post all of the applicable information we can provide on each article page -- that doesn’t include the published date or sources. Generally, the accessed date works for bibliographies calling for a date. You’ll find the author's name and all information at the left of the article, under "Article details."
Check out the related question in our FAQ for more information about citing to wiseGEEK articles: http://www.wisegeek.com/faq.htm
Best of luck with your project!
